About

This study evaluates postoperative pain and radiographic healing of asymptomatic posterior teeth with chronic apical periodontitis following root-canal treatment performed using EndoActivator for irrigation activation.

Full description

Aim: To evaluate postoperative pain and radiographic healing of asymptomatic posterior teeth with chronic apical periodontitis following root-canal treatment performed using EndoActivator for irrigation activation.

Methodology: In this clinical trial, root-canal treatment was performed on 140 posterior teeth with chronic apical periodontitis. After routine canal preparation, patients were assigned to either a control group treated using conventional needle irrigation (CNI) without activation or to sonic irrigation activation with EndoActivator. All treatment was completed in a single visit. Patients provided self-assessments of the severity of postoperative pain at 1, 2,3 and 7 days using a Verbal Rating Scale (VRS) and Wong Baker Face Scale. Patients were recalled at 12 months for clinical and radiographic examinations. Periapical healing was evaluated using a periapical index (PAI), with scores of 1 or 2 considered to represent treatment success and scores of 3, 4, or 5 to represent treatment failure. Data were analyzed using one-way ANOVA and Kruskal-Wallis tests, with differences of P < 0.05 considered statistically significant.

140 participants in 2 patient groups

Sonic Activation with EndoActivator

Experimental group

Description:

Sonic irrigation was performed using an EndoActivator sonic handpiece (Dentsply Tulsa Dental Specialties, Tulsa, OK, USA). A suitable-size activator tip was selected and loosely placed at 2 mm from working length, and the device was operated at 10,000 cycles/min using a pumping action to move the tip to produce vertical strokes of 2-3 mm.

Treatment:

Procedure: Sonic Activation with EndoActivator

Conventional needle irrigation (control)

Active Comparator group

Description:

Conventional needle irrigation was performed with short, in-and-out vertical strokes of 2-3 mm at a rate of approximately 100 strokes per minute.

Treatment:

Procedure: Control Needle Irrigation
